ELECTRICALLY-HEATED 00MB.

To all whom t may concern Be it known that l, EDWARD SCHWARTZ, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of ,lllinois, have invented certain new and useful Improvements in Electrically' Heated Combs, of which the following is a specification.

The-main objects of this invention are to provide an improved form of electrically heated curlingiron and comb wherein the curling iron shield and comb are each adapted to be detachably secured to the electric heater and rigidly held in position thereon; to provide an improved construction of the electric heater and housing therefor; and to `provide an improved form of electrical connection between the heating element and the conductors leading to the` source o-f electricity.

An illustrative embodiment of this inventionis shown in the accompanying drawings, in which?n Figure 1 is a perspective view of a device constructed according t-o this invention and having the curling iron shield in position thereon. Fig. 2 is a longitudinal sectional elevation of the device adapted to serve as a comb removed from the heater. Fig. l'is a front end view of the heater with the comb removed. Fig. 5 is a fragmentary detail illustrating the position of the notch in the comb-back. Fig. 6 is an enlarged sectional detail of the curling iron shield and the part of the heater adjacent to which it is attached. l

lln the construction shown in the drawings, the comb 1 is formed from a piece of sheet metal or a casting, and has a plurality of teeth 2 cut or formed therein of the usual shape, and the back 3 is provided with a i ment being constructed in the form of a rod or tube 7 of insulating material, placed upon a metal reinforcing tube 8 and upon which is wound the resistance wire 9. The heating element is free to rotate as a unit relatively to the casing upon the rings 10. The casing 5 is provided with a handle 11, of

wood or other heat insulating material, and has extendingforwardly therefrom a flange 12, concentric with the casing 5, and spaced away therefrom to form an annular recess 13, into which the end la of the comb back 3 is received. A shoulder 15 is formed on the casing 5 within the recess 13, which is adapted to be received into a notch 16 in the end 14 of the comb back 3, when the comb is placed upon the casing 5. The shoulder and notch secure the comb and heater against relative rot-ation.

`When the comb is removed, the heater may be used in the usual manner as a curling iron. A shield 17 is usually used with 70 i the heater when curlingis done. The shield 17 fits over the tube 5 and is secured tothe heater by a clip or saddle 18, to which itgls-j pivoted at 19. rlhe saddle 18 is designed tog' be retained in the recess 13 and secured 75.

against displacement by the spring 20, which embraces the pivot 19, and has one part bearing against the under side ofthe rear end of the shield 17 (Fig. 6), and the other part seated in the groove 21 on the 80 flange 12. The shield 17 is provided with a thumb button 22 for operating the shield.

Electrical conductors 23 in the form of a cord are provided with the usual socket plug 24 andare seciired to the end of the handle y85 11 for connecting the heating element 6 with a source of electricity. The electrical connection between the heating element 6and the conductors 23 is completed within the handle 11. This connection comprises a pair of sockets or vtubular contacts 25 carried by a block of vinsulating material 26 rigid on the rrod 27 extending rearwardly from the heating element` 6, and resilient rods 28 carried in the block 29 of insulating 95 the tube 8 at its forward end. The other 105 tube 25 is electrically connected tov the rod 27 by a lll-shaped member 31 secured lin the block 26 to bear against said tube and rod. rlhe rods 28-,are respectively connected to the conductors 23, being clamped at their 11o One of ends over the ends of said conductors and retained in a disk 33 adapted to be received in the end of the block 29. A second disk 34 is placed'inward of the disk 33, which holds the conductors 23 and rods 28 apart. The rods 28 are normally sprung apart or bent so that when they are inserted into the tubes, a firm contact between the rods and the tubes is obtained. The outer block 29 has rotary connect-ion with a sleeve 35 and is threaded into the handle to secure the heating element against being accidentally withdrawn.

To operate the device, the socket plug 24: is screwed into a lamp socket in the usual manner. The connection between the heating element and the conductors 255 need not be disturbed for this purpose, as the rotation of the heating element will remove the twist from the cord. The double prong and socket connection between the cord and heating element enables them to be readily connected or disconnected and is not disturbed 1n any way by a torsional strain on the cord as the plug is screwed into the line socket.v

means for transferring heat from the heater to the prongs. The shield 17 is quickly and conveniently placed upon 'the heater 5 by 'slipping the saddle 1S under the flange 12 and the spring 20 into the groove 2l.

Although but one specific embodiment of this invention is herein shown and deeribed, it will be understood lthat some of the details of the construct-ion shown may be altered or omitted without departing from the spirit of this invention, as defined by the following claims.

I claim 1. In a device of the class described, the combination of a casing, a handle attached thereto, a heating element housed in said casing, a comb having a bore formed in the back thereof adapted to receive said casing, and a coacting notch and shoulder on said casing and comb back for securing them against relative rotation.

2. In a device of the class described, the combination of a casing, a handle attached thereto, a heating element housed in said casing, a comb having a bore formed in the back thereof adapted to receive said casing, and a shoulder on said casing, and said comb back having a notch therein adapted to receive said shoulder for securing said comb and casing against relative movement.

3. In a device of the class described, the combination of a casing, a heating element housed in said casing, a 'handle attached -thereto and having a flange arranged concentrically with respect to said casing so as to provide an annular recess between said casing and ange, a comb having a bore formed i-n the back thereof adapted to receive said casing and having the end of said back shaped to fit in said recess, and a shoulder located in said recess, said back having a notch therein adapted to receive said shoulder for securing said comb and casing against relative rotation.
